X10 est un langage de programmation en cours de développement par IBM au centre de recherche Thomas J. Watson financé par le projet High Productivity Computing Systems de la DARPA. Les auteurs principaux sont Kemal Ebcioğlu, Vijay Saraswat, and Vivek Sarkar.
X10 est conçu pour la programmation parallèle avec le modèle d' (PGAS). Un programme s'exécute sur un ensemble de places : chaque place possède des données et quelques activities qui font des calculs sur ces données. Il supporte un système de typage avec des contraintes pour la programmation orientée objet, les types primitifs structs définis par l'utilisateur, les globally distributed arrays et le parallélisme structuré et non structuré.

Computer simulations of experimentally comparable system sizes in soft matter often require considerable elapsed times. The use of many cores can reduce the needed time, ideally proportionally to the number of processors. In this paper a parallel computati ...
The growing use of multicore and networked computing systems is increasing the importance of developing reliable parallel and distributed code. Unfortunately, developing and testing such code is notoriously hard, especially for shared-memory models of prog ...
Chapel, the Cascade High Productivity Language, is a parallel programming language that was developed by Cray, and later by Hewlett Packard Enterprise which acquired Cray. It was being developed as part of the Cray Cascade project, a participant in DARPA's High Productivity Computing Systems (HPCS) program, which had the goal of increasing supercomputer productivity by 2010. It is being developed as an open source project, under version 2 of the Apache license. The Chapel compiler is written in C and C++ (C++14).
In computer science, partitioned global address space (PGAS) is a parallel programming model paradigm. PGAS is typified by communication operations involving a global memory address space abstraction that is logically partitioned, where a portion is local to each process, thread, or processing element. The novelty of PGAS is that the portions of the shared memory space may have an affinity for a particular process, thereby exploiting locality of reference in order to improve performance.
In computing, a parallel programming model is an abstraction of parallel computer architecture, with which it is convenient to express algorithms and their composition in programs. The value of a programming model can be judged on its generality: how well a range of different problems can be expressed for a variety of different architectures, and its performance: how efficiently the compiled programs can execute. The implementation of a parallel programming model can take the form of a library invoked from a sequential language, as an extension to an existing language, or as an entirely new language.
The Simple Object-Oriented Concurrent Programming (SCOOP) model proposed by Bertrand Meyer and illustrated through the Eiffel programming language is a simple yet powerful model for concurrent programming. In this paper, we analyze the applicability of the ...
